Trial Parameters
Brief Summary
The goal of this observational study is to analyse the cartilage and bone forming potential of cells isolated from the tissues of patients undergoing surgery for the treatment of polydactyly, hip dislocation and from other bio-banked cartilage tissues. The main question it aims to answer is: Which of the following tissues from polydactyly digit, iliac apophysis or other bio-banked cartilage produce better cartilage in vitro and in vivo? Participants receiving digit amputation surgery for treatment of polydactyly will be asked to donate the associated waste tissue whilst participants receiving surgery to treat a dislocated hip will be asked to donate an extra small piece of cartilage tissue (approximately 1 gram) from the iliac apophysis. Other tissues for the study will be obtained from those donated to biobanks.
